There are three ways to encode different data in PDF417. Nine hundred of these code words were designated for data storage, while the remaining 29 for specific functions. Ynjiun’s barcode design was competent and could store up to 929 obtainable code words.

Schedule a free identity verification demo here. Verify customers identity within 15 seconds. To decode the data, a scanner device would scan and change the image on the carrier into electrical signals that represent the image. The image would store all the data encoded and then printed over a paper or other carrier form. The idea behind PDF417 was to develop a technique for encoding and decoding data in a machine-readable visual structure. While two graduate students invented the first barcodes: Bernard Silver and Norman Joseph Woodland from Drexel Institute of Technology, Philadelphia, in 1952, it was Dr. So, how does PDF417 work, and how does it help in identity verification?

PDF stands for Portable Data File, while 417 represents four bars and spaces and a 17-part codeword. The PDF417 barcode is a variable-length, 2D stacked barcode that anyone can use to store binary data. Among its many forms, PDF417 is a popular barcode type that is in use today. Representing data through a machine-readable format is an effective way that is used worldwide: from government documents to grocery billing, etc. A barcode is a simple way of data representation through a visual, machine-readable form.
